Inspection and Preventative Maintenance Checklist
Complete a visual inspection of the mill before the beginning of each production
day and look for loose, worn, broken or defective parts.
Check hydraulic fluid and blade lubricant levels. We recommend
Dexron/Mercon III transmission fluid for hydraulic fluid.
Grease the clamp arm up/down & in/out; fence arm up/down; and toe roller
up/down. We recommend JT-6 grease.
Grease the linear bearing on the guide arm and head raise/lower rails. We
recommend JT-6 grease (no more than 1 pump for each).
Lubricate ball screws (1 per side) with spray grease. We recommend Zep 2000.
Lubricate the log turner chain. We recommend Zep 2000 or heavy oil.
Clean the crown on the idler and pull wheels using an air hose, brush or by
wiping them down, freeing them of dust and debris.
Clean & inspect the blade guides. Excessively worn guides should be replaced.
Check band blade tension ensuring proper pressure for the size of blade in use.
2” blade = 1,900 - 2,100 PSI; 1 ½” = 1,700 PSI
Check band blade tracking. A 2” blade should be centered on the wheels with
the gullet flush or no more than 1/32” past the front face of the wheels.
A 1 ½” blade should be centered on the wheels the same distance from the
gullet to the wheel and back edge of the wheel to the back edge of the blade.
Check power band belt and ensure tension is “taut” with no more than 1/2” of
deflection in the belt.
Lubricate the carriage drive chains (1 per side). We recommend Zep 2000 or
heavy oil.
Clean carriage wheel rails (1 per side) using an air hose or brush.
Check the tailing or off-load conveyor for proper tracking. If necessary, modify
tracking with the adjustment bolts that connect to the belt extender.
Remove guards and covers on the carriage and check the raise / lower drive
assembly.
Look for belt wear such as dry rot or stress cracks. Change prior to failure.
Check tension on the main drive belt and the left and right raise / lower belts,
ensuring belts are “taut” with no more than 1/2” of deflection.
Grease the top and bottom bearings that hold the left and right ball screws. We
recommend JT-6 grease (no more than 3 pumps).
Grease the carriage drive shaft. We recommend JT-6 grease (no more than 3
Grease the tailing or off-load conveyor wheel bearings. We recommend JT-6
grease (no more than 3 pumps).
Remove guard from the tailing conveyor and check chain tension. Tension
should be “taut” with no more than 1/4” deflection in the chain. Adjust tension
via the two (2) idler sprockets.
Every 2 years
(2,000 – 3,000 hrs)
Have idler and pull wheel crowned.
** RETURN ALL GUARDS AND COVERS PRIOR TO RESUMING OPERATION! **
Improper lubrication
will void warranty.
